Factory settings:
Depending on the type of the O
2
sensor,
one of the two O
2
control ranges has been
preset at the factory:
Control range I: 1% to 21%
Control range II: 5% to 90%
Usage of the process gases:
For set values below 21% O
2
, the device
must be connected to a nitrogen supply
system.
For set values above 21% O
2
, the device
must be connected to an oxygen supply
system.
Since the O2 concentration of the air is
nearly 21%, the O2 control and the control
loop error monitoring system are disabled
at a set value of 21%.
The control loop error monitoring system
(optional) is enabled.
